+ contrib/rddads/adsx.c
+ added implementation of local indexing support for ADS driver.
Local indexing is used in case server can not do index
creation, for example: index key depends on relation child area
fields, index key uses user defined functions, index is created
using codeblock, but not expression, etc.
; This code implements no update index! Partial index update could
also be implemented, but I didn't have a need for this. Besides
that partial index implementation will be a little more
complicated than in other RDD. Database update operations are
not done in a single goCold() method. So, index update should
be called, from many methods: append(), putValue(), delete(),
recall(), etc., or ADS RDD structure should be changed to
support real goCold(). For implementation of partial index,
I'd suggest to use tree index (instead of a simple sorted array
and binary search). B-tree code could be found in
contrib/rddsql/sqlmix.c.
; Please check makefiles, and other compilers, platforms.
